AUTOMOBILE RADIATOR VENTILATORa Application filed January 11, 1928.Serial No. 246,069.

This invention relates to ventilators use 111 in connection with theradiators of automobiles, more particularly to a type capable ofattachment at the filler openings of the radiators.

The main object of my invention is to provide for eilective circulationof air through the upper headers of automobile radiators above thesurface of the liquid. cooling medium therein to the end ofcounteracting vapor pressure and preventingexcessive evaporation throughboiling, especially when highly volatile liquids, such as alcohol or thedifferent compounded solutions now available on the market, are employedas cooling agents for cold weather driving. 2 v

My invention is further concerned with provisions to automaticallycontrol circulation of cooling air through the radiator in accordancewlth temperature conditions therein; as well as with provisions wherebythe ventilators may be rendered inoperative when desired.

How the foregoing as well as still other objects and attendantadvantages may be readily realized in practice will be manifest from thedetailed description which follows of the typical embodiment of thisinvention delineated in the drawings.

' \Vith reference first more .in detail to F 1 to IV oi" theseillustrations, it will be observedthat the ventilator of my inventionembodies a flat hollow circular head 10 wherefrom depends a tubularshank or stem 11, which, in the present instance, is integrally formedwith said head. As shown in Fig. Lthe stem 11 extends down into theupper header 13 of the automobile radiator through a central aperture inthe screw cap 14: overthe neck 15 about the fillin g opening. The screwcap 14 is secured to the ventilator by a clamp nut l6which opposes acircumferential stop flange 1701i the stem 11 and engages the screwthreaded portion 11 of the latter. interiorly by a central verticalpartition 18 through the medial plane of the head 10 with provision, insaid head, of horizontal axially-aligned circular anterior and posteriorair influx and efllux openings 19, 20, and through the stemllfrespectively communicating vertical inflow and outflow duets 21, 22which terminate at the lowerend of the stem 11 within the radiatorheader 13,- To

in laterally directed openings 21 22 facilitate angular flow of the airbetween the influx and efllux openings 19, and the communicatingvertical ducts 21, 22, I employ, crosswise of said openings, deflectorvanes 25, 26, which, as shown in Fig. I, are arcuate in cross sectionwith their inner edges extending into closer proximity to the quence ofthis arrangcment,.the air flow is proportionately and uniformlydistributed incidental to passageinto and out of the vertical flow ducts21, 22. The vanes 25, 26, are supported at opposite ends by periinetricmembers 27, 28, in the present instance in the form of flange ringshaving a friction fit within count-o1. recessions 29, of the head 10. 1l

3111 order thatthe device may. be rendered inoperative at will, I mayequip either or both the removable vane-supporting inserts with a shutoil valve'such asshown in Figs. l, 11 and V, having tl e form of a splitband 31 with hearing at the inside of the ring flange 27. At the bottom,the valve s a cut out 32 for normal registry lei? the The ventilator issubdivided duct 21. A lateral projection or tongue 33 of the valve band31 extends through an arcuate motion limiting slot 8% in the flange ring27 and serves as a manipulating handle, see Figs. II and III moreparticularly. The port 32 may be protected by wire mesh screening asconventionally indicated in Figs. I, III and V to preclude entry of dustinto the radiator with the air.

For the purpose of automatically controlling the flow of air through theradiator in accordance with temperature conditions within it, I provide,as shown in Fig. I, a sleeve valve around the lower end of the stem 11.This sleeve valve has ports 36, 37 for registry with the lateralopenings 21, 22" of the vertical air flow ducts 21, 22, and is securedto the upper end of a conventional bellows thermostat 38. At the bottom,the thermostat 38 is attached to a plate 39 which immovably supported byscrews d0 taking into a fixed collar a1. on the stem 11.

The operation of the device is as follows: Incidental to travel of theautomobile, air forced into the anterior influx opening 19 of the head10, and directed, by concerted action of the deflecting vanes 25,downward into the vertical inflow duct 21 for discharge through thelateral outlet 21 and induction into the frontal portion of the radiatorheader 13 as indicated by the arrows inFig. I. An air pressure is thusset up within the radiator head with resultant dis placementconcurrently of a corresponding amount of air therefrom, escape being byway of the lateral opening 29f into the vertical outflow duct 22, andthence into the posterior efilux opening 20 of the head 10 where thedeflecting vanes 26 redirect the air for horizontal rearward dischargefrom the ventilator. In this way, it will be seen that air is constantlycirculated through the upper header of the radiator over the surface ofthe liquid medium therein to assist in maintaining it cool, therebycounteracting and carrying oil vapor pressure and at the same timepreventing excessive evaporation. Operation as just described is ofcourse subject to control by the sleeve valve under governance by thethermostatic bellows 38, in accordance with the temperature within theradiator. In other words, in pract .e, as the temperature within theradiator rises and the bellows 38 expands, the sleeve valve 35 isgradually moved upward from the full closed position when the motor iscold (as at starting), to full open or illustrated position in contactwith the collar 41, with attendant variation in the air flow.

Figs. VIII and IX show an alternative form of automatic flow control inwhich the thermostatic bellows 38* is attached to the lower end of thestem 11, and enclosed by the sleeve valve 35* which it carries.

Thus as the bellows 38 expands, the sleeve valve 35* is moved downward(instead of upward as in Fig. I) to bring its ports 36*, 37* intoregistry with the lateral openings 21 22 of the vertical iiow ducts 21,22.

In instances when the thermostatic control is not desired, I may employ,instead of the filtering screen on the shut-01f valve 31, a collar suchas shown at 42 in Figs. VI and VII to fit the lower end of the stem 11and having perforations 1-8 distributed over areas corresponding to theopenings 21, 22 into the vertical ducts 21, 22. The screen collar 12 isdetachably held in place through cooperation of bayonet-lock notches itin its upper edge with studs projecting laterally from the stem 11.

From the foregoing it will be seen that I have provided a very simpleand ellicient means for setting up circulation of air within the upperheader of the radiator with attainment of the various advantageshereinbefore pointed out. I do not wish to be limited to the precisedetails of construction herein shown since my invention is capable ofcmisiderable modification; for example, the ventilator may beconstructed il'itegral with the radiator cap 14, and the head 10 madeotherwise than circular. Also, the stem 11 may, either in whole or inpart, be made separate from the head 10 if found convenient from thestandpoint of economical manufacture.
